Google’s market share rose two-tenths of a point, from 66.7 percent in September to 66.9 percent in October. Bing gained a tenth of a point and reached 16 percent in October. Both of those numbers represent all-time highs using comScore’s estimates. Yahoo was static for the month and Ask’s share was down.

Desktop search activity was up significantly in October, too, following a general decline over the past several months.

ComScore estimated that there were about 17.6 billion desktop searches in October, up eight percent from September.

That’s still down, however, from the previous high of 18.4 billion desktop searches, which was set in March 2012. It’s indicative of the rising amount of mobile searches, which we’ve explained before is estimated at between 12 and 30 percent of all searches depending on the category.
